July 4;, 1933:. J. F. PATTERSON PLAYGROUND APPARATUS Filed March 19, 19750 Patented July 4, 1933 STATES JAMES F. PATTERSON, OF SAN JOSE, CALIFORNIA PLAYGROUND APPARATUS Application filed March 19, 1930.

This invention relates particularly to an exercising device for children or adults.

It is the object of the invention to provide a device whereby the operator may follow an endless path of travel while swinging freely from an overhead structure, and one in which either arm may be subjected to a greater amount of exercise than the other according to the direction of movement.

It is also an object of the invention to pro vide a device of the character indicated in which the arms of the operator may be subjected to unequal or equal exercise as desired.

It is another object of the invention to provide a device of the character indicated that will be simple in construction, economical to manufacture, strong, durable, and highly efficient in its practical application.

In the drawing:

Figure 1 is a perspective illustration of one embodiment of the invention.

Figure 2 is a plan view of one half of another embodiment of the invention.

Referring now more particularly to the drawing, I show at l a suitable standard or supporting member set in a concrete base 2.

Fixedly mounted on the standard a distance below its upper end is a collar 3, and seated in the collar 3 are a plurality of radially disposed elements as 4.

Mounted upon the outer portions of the radial elements 4 and in concentric relation to the standard 1 are a pair of spaced annular hand bars as 5 and 6. The bars 5-6 are secured to the elements 4 in any suitable manner as by bolts 7-8, and the parts thus assembled are supported in a given position by tie rods 9 seated in a collar 10 on the top of standard 1 and engaging the bolts 8.

In use, the operator grasps a bar 56 in each hand and then travels around the structure by swinging forwardly and grasping one bar in advance of the other, alternately.

Since the bars 56 are of difierent diameters it follows that when travelling in the direction indicated by the arrow 11 a preponderence of work will be thrown upon the right arm, while in travelling in the opposite direction as indicated by arrow 12 the oppo- Serial No. 437,045.

site condition will prevail. This difierence in work required may be utilized in building up one side of the. body with respect to the other in a natural and normal manner.

In the embodiment of the invention shown in Figure 2 the annular bars 56 are used as supports for a plurality of short radial bars or rungs 13. These rungs are equally spaced along bars 5-6 so that the user may travel in either direction with the work equal- 5 1y distributed to the opposite sides of the body.

It may now be readily seen that in both of these embodiments of the invention the operator may travel around as long as his strength will permit, permitting their use in endurance tests. Furthermore, two or more operators may use the device at one time thereby permitting competition in ensupporting means, and a pair of hand-bars forming rings of different diameters concentrically and horizontally disposed thereon and spaced from the ground to permit a child to swing freely therefrom and arranged for permitting the user to travel therealong in- (I definitely in one direction by swinging alternately from one bar to the other.

2. An exercising apparatus comprising, supporting means, and a pair of horizontallydisposed hand-bars forming rings of different diameters concentrically disposed thereon and spaced from the ground to permit a child to swing freely therefrom and arranged for permitting the user to travel thcrealong indefinitely in one direction by swinging al- P ternately from one bar to the other, and a plurality of spaced radially disposed handbars mounted on and connecting the first mentioned hand-bars.
